Risk assessment is the systematic recording and evaluation of all factors in the work process that can cause occupational injuries, illnesses or health damage. It can identify the options, ways of preventing, eliminating and reducing risks.The risk assessment considers the work organization, work processes, raw materials and materials used in technological and work processes, personal protective equipment and equipment at work, as well as other elements that may cause risk of personal injury, health damage or illness of the employee.The primary objective of occupational risk assessment is the protection, safety and health of employees.Risk assessment helps to minimize the risk of employees being compromised during work process activities. It also helps to maintain the efficiency of the business activity.A risk assessment act is an act containing a description of the work process with an assessment of the risk of injury and / or damage to workplace health in the work environment and measures to eliminate or reduce risks in order to improve safety and health at work.This act determines the possible types of hazards and harms in the workplace, assesses the risk of injury at work or health damage of the employee, determines ways and measures to eliminate them, or reduce their risk to minimum.Mechanical engineers design machines and tools, organize their production and handle their exploitation. They are experts for propulsion engines, vehicles and vessels, process and power plants, load-bearing structures. As designers, they design a product or manufacturing process so it can best meet the requirements and functions they need. In a process of designing a product, they take available raw materials and available production technology, and if they design the production process, they are guided by the type of input material and processing technology. Mechanical engineers in manufacturing plan, manage and supervise the production of machinery and plant. They systematically test the manufactured components, because they depend on the efficiency, reliability and safety of the whole system. For quality assurance, they constantly carry out tests and measurements of input materials and finished products with measuring instruments.This work is based on an analysis of the position of a mechanical engineer in the company named "Flamma-Systems Ltd." based in Nis. The company employs mechanical engineers and it deals primary with manufacturing of high-power boilers for heating greenhouses and buildings. The main market for this company is Sweden.

Palm oil industry in Indonesia has been growing rapidly. But, unfortunately the growth is only effective on upstream industry with low value products, such that potential downstream value added are not explored proportionally. The government is therefore in the process of developing an appropriate policy to strengthen the national palm oil downstream industry. This paper proposes that an approriate policy for developing palm oil downstream industry could be derived from the maps of value chain and existing technology capability of the industry. The result recommends that government policy should emphasize on the supply of raw materials, infrastructure and utilities, as well as developing the missing value chain industry, especially ethoxylation and sulfonation.

This chapter describes occupational injuries and their prevention. It describes in detail the causes of injuries and epidemiology of injuries. Occupational injuries are caused by acute exposure in the workplace to safety hazards, such as mechanical energy, electricity, chemicals, and ionizing radiation, or from the sudden lack of essential agents, such as oxygen or heat. This chapter describes the nature and the magnitude of occupational injuries in the United States. It provides data on risk of injuries in different occupations and industries. Finally, it discusses prevention of injuries, using a hierarchical approach to occupational injury control.

Man-made organic waste leads to the rapid proliferation of pollution around the globe. Effective bio-waste management can help to reduce the adverse effects of organic waste while contributing to the circular economy at the same time. The toxic oily-biological sludge generated from oil refineries’ wastewater treatment plants is a potential source for biogas energy recovery via anaerobic digestion. However, the oily-biological sludge’s carbon/nitrogen (C/N) ratio is lower than the ideal 20–30 ratio required by anaerobic digestion technology for biogas production. Sugarcane bagasse can be digested as a high C/N co-substrate while the oily-biological sludge acts as a substrate and inoculum to improve biogas production. In this study, the best C/N with co-substrate volatile solids (VS)/inoculum VS ratios for the co-digestion process of mixtures were determined empirically through batch experiments at temperatures of 35–37 °C, pH (6–8) and 60 rpm mixing. The raw materials were pre-treated mechanically and thermo-chemically to further enhance the digestibility. The best condition for the sugarcane bagasse delignification process was 1% (w/v) sodium hydroxide, 1:10 solid-liquid ratio, at 100 °C, and 150 rpm for 1 h. The results from a 33-day batch anaerobic digestion experiment indicate that the production of biogas and methane yield were concurrent with the increasing C/N and co-substrate VS/inoculum VS ratios. The total biogas yields from C/N 20.0 with co-substrate VS/inoculum VS 0.06 and C/N 30.0 with co-substrate VS/inoculum VS 0.18 ratios were 2777.0 and 9268.0 mL, respectively, including a methane yield of 980.0 and 3009.3 mL, respectively. The biogas and methane yield from C/N 30.0 were higher than the biogas and methane yields from C/N 20.0 by 70.04 and 67.44%, respectively. The highest biogas and methane yields corresponded with the highest C/N with co-substrate VS/inoculum VS ratios (30.0 and 0.18), being 200.6 mL/g VSremoved and 65.1 mL CH4/g VSremoved, respectively.

An underdeveloped country wishing to establish a fertiliser industry ought surely to begin by examining the locally available raw materials. In Tanzania, for example, a report in 1961 drew attention to an anhydrite deposit at Kilwa which could have been used to produce cement, gypsum, and sulphuric acid.2 The latter if combined with ammonia from the oil refinery would have given ammonium sulphate, the fertiliser most commonly used in Tanzania. The report also noted three deposits from which phosphatic fertiliser could have been made. However, the development of these local resources was rejected on the ground that for plants of an efficient size the local market would not be able to absorb all the fertilisers.

In recent years, there has been a trend in the global oil industry to improve the proportion of heavy high-sulfur crude oils in the total volume of extracted and processed resources, reserves of which are estimated at over 800 billion metric tons. Therefore, the main line of oil refining is processing of heavy crudes and residua to allow maximum use of the hydrocarbon potential and yield of high-margin products. Hydrogenation processes of heavy raw materials are most attractive in terms of product quality. This article analyzes tar hydrocracking processes that are either in operation or at the stage of full-scale testing. These include Veba Combi-Cracker (VCC), Uniflex, suspended-bed catalyst hydrocracking (ENI), and vacuum residue hydroconversion (TIPS RAS). These technologies use heterogeneous catalysts and are designed to obtain the largest possible amount of liquid products. This article discusses the features of each technology, highlights their advantages and disadvantages, shows the main approaches to process management, and speculates about the development of these technologies. Tar refining is a major process in heavy oil upgrading, and the development of efficient tar-processing methods will influence refinery configurations and management.

Suppliers are extremely important in business operations. The supplier ensures the supply of materials, raw materials, commodities, etc. in sufficient quantity, quality, stability, and accuracy to meet the requirements of production and business with low costs and on-time deliveries. Therefore, selecting and managing good suppliers is a prerequisite for organizing the production of quality products as desired, according to the schedule, and with reasonable prices and competitiveness in the market. It is also important to gain the support of suppliers in order to continue to improve and achieve more as a business. The evaluation and selection of a supplier is a Multi-Criteria Decision-Making (MCDM) issue, in which the decision-maker is faced with both qualitative and quantitative factors. In this research, the authors propose an MCDM model using a hybrid of Supply Chain Operations Reference metrics (SCOR metrics), the Analytic Hierarchy Process (AHP) model, and the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) approach for supplier evaluation and selection in the gas and oil industry. Using literature reviews on SCOR metrics, all criteria that impact supplier selection are defined in the first stage, the AHP model is applied to determine the weight of each factor in the second stage, and the optimal supplier is presented in final stage using the TOPSIS model. As a result, Decision-Making Unit 5 (DMU-05) is found to be the best supplier for the gas and oil industry in this research. The contribution of this work is to propose a new hybrid MCDM model for supplier selection in the gas and oil industry. This research also introduces a useful tool for supplier selection in other industries.

The explosive development of the human society in contrast to the limited character of resources determines the need for successful implementation of mathematic models in the decision-making process concerning the use of available resources. The oil industry includes a series of global processes such as mining, extraction, refining, transport (road, rail, ship and pipeline) and oil products. The products of this industry with the highest degree of utilization are gasoline and diesel but the portfolio is much broader, kerosene, bitumen, fuel and raw materials for other chemicals such as solvents, pesticides, fertilizers and materials plastic. The oil industry comprises three major areas: "upstream" extraction; refining - "midstream" and transportation and marketing of downstream products. In most cases refining is considered to be part of downstream, Oil and petroleum products are essential for many industries and their importance is vital in maintaining and developing the industrial area in the current configuration.
